Overview High Voltage Power Supplies

The M-Power-Line impresses with its robust design, high efficiency, compact dimensions and outstanding price-performance ratio. Thanks to the use of a Power Factor Controller (PFC), the input voltage can vary from 100 to 254 V. This allows the device to be used anywhere in the world, regardless of the power supply system in the specific country. With its simple operation and easy readability of relevant parameters (set/actual/status), the devices are especially attractive for use in many branches of industry, as well as in research institutes.

In principle, the rectified line voltage drives a square wave generator of fixed frequency, whose AC voltage is transformed, rectified and filtered, producing the output voltage. For regulation, the square wave voltage is pulse width modulated.
A low residual ripple of the output voltage, together with a high stability, high regulation speed and a low stored energy are all achieved by virtue of the high switching frequency.

The mains voltage is transformed to high voltage potential. Either on the primary side or on the secondary side, a phase cutting circuit with thyristors is installed. The rectified voltage is smoothed by a LC-filter.
